Rear Wheel Steering... Why Not??

[Shismo]

Hi Guys,

I was wondering whether it was possible to implement rear wheel steering to FWD car? I guess it would solve the Torque Steer issue and would also be less expensive to build than RWD car. I wonder what the handling characteristics will be of such a car? Oversteer? Understeer?

I know this sort of setup was used on the ThrustSSC project for the land speed record.

Let me know your thoughts on this guys..

Thanks

If you could source parts in SL, why not try

Btw what is the car?

There have been cars with rear wheel steering mechanisms - one such example would be the Super HICAS system on the Z32 300ZX's

but the application you should look into is the Honda Prelude - Front wheel drive car with 4 wheel steering

Ahem. HICAS was available on the 4 wheel drive GT-Rs too. You should look into Hondas my behind! But anyway, those are very limited angles. I think this post is talking about handling all the steering through the rear wheels and leaving the front wheels to put the power down only. I guess it might be possible with EPS or steer-by-wire, no need to physically connect the steering wheel to the steering mechanism. Tho thats zero feel for driving enthusiasts.

if u remember the meroon/green R33, it had HICAS, when the car is taking a corner 80KMH+ rear wheels rurn, it look so sweet, but the HICAS test ended with a Drifting competition and it ended with bold tyres

i doubt it'll kill understeer or oversteer. and those systems are strictly limited to low speeds if i'm right. plus you might not generate enough lock to activate the system at high speeds.

either way i'd stay clear away from those systems cos i kno its going to be a surreal feeling having the rear move about in corners.

5th gear tested a laguna with 4ws sometime back. if you find that clip on streetfire that oughta give you a good understanding on why its not really that great in real life

take a Fork Lift for a short spin and you'll know why rear wheel [only] steering is not the brightest idea

[MasterDon]

i once saw on "extreme machines" a fire truck with a seperate driver to steer the rear wheels...maybe you could try that approach

[outlander]

Hmmmm Most seems dosent like rear wheel drive !!!

Lets take a Lancer box (rear type), have seen meny of them running day to day in roads...

Heard that rear wheel driving is effect slightly negative in fuel efficency...

Driving n handling is not that difficult, even without power stering...

i dunno about fuel economy, but try putting about 200 horses down through the rear in the wet - i guarantee you'll be suprised!

its not rear wheel drive thats the question here , but rather rear wheel STEERING , where the rear wheels actually turn..

Man, you need to pay more attention. We weren't even talking about rear wheel drive, its on rear wheel steering.

Try putting down 200 horses thru the front wheels on the wet

"they" should try it together n see who gets more sideways off the line!

back to original topic,

draw back of having rear wheel steer is the turning is not as sharp as front wheel steer. Imagine this, you see an oncoming vehicle occupying most of your lane, and you cut into left to avoid. If you had rear steer, then the back of the vehicle will first move towards right before it really moves the "nose" of the vehicle towards left..

He was talking about RWD from the start, but has posted a wrong title, maybe

in contrary, he was talking about avoiding torque steer or FWD cars by having rear wheel steering I guess.

I'll prefer rear wheel drive anyday over front wheel drive

we are talkin about rear wheel steering here

The original posting is confusing and you guys are thinking both ways when the actual question is not clear enough...

Rear Wheel steering to a Front Wheel Drive car, wow I guess it is like driving the car on reverse! He he.... One crazy fellow did that kind of thing to a Fiat 126! Well for ideas on how it would turn out to be see this----> http://www.youtube.com/watch?v=WlC93lTEwBQ

mt two cents ....

Personally i would imagine rear-wheel steering to be quite wobbly.. but might not be that bad in small doses.

Yo! there is nothing confusing with the original post - real wheel steering in a FWD car - that's as clear as it could be put

looks like few of us were confused, but he was talking about rear wheel steering, not RWD. But am wondering how it could be less expensive compared to getting a RWD or doin other mods to overcome torque steer or anything, unless your designing cars for a car manufacturer. I'd rather get a car with ATTESA lol

didn't really think of it like that , but thats excellent logic!

am i seeing things or does that car have 2 drivers able to manouver both sets of wheels whilst being able to drive it in the "wrong" direction?

crazy sh*t!

you and a few more i recon

but i began to wonder what aside from the GTR's had both the ATTESA & HICAS and suprise suprise i ended up with a Bluebird!

Ref the SSS-R section at the end!
